Optimizing the location of piezoelectric sensors
Original language description
Piezoelectric sensors appear to be best suited for picking up acoustic signals thanks to their high sensitivity over a wide frequency range, frequency response stability, design compactness and reliability. Their design differs from sensor to sensor, depending on the type of the measurement to be carried out. Piezoelectric sensors are manufactured on the basis of crystals and polarized dielectrics. They feature, above all, a very good signal-to-noise ratio, a fast response to the load change and a widerange of operating temperatures. Along with the measurements of the noise voltage spectral density, the sensor sensitivity measurements are of high importance not only for the development of acoustic methods but also for the sensor application and, aboveall, checkout. The present paper deals with our test results of piezoelectric sensors from the following viewpoints: frequency range, response uniformity, sensitivity and optimum location of a selected sensor with regard to the amplitude
